So, IOTL, after the end of WW2, the Allies decided that "Prussian Militarism" was responsible for WW2, and officially dissolved Prussia as a geopolitical entity, complete with mass deportations of Germans from the new Polish lands (which is nothing on the Holocaust, but was still a pretty bad thing to do).
However, this doesn't really make much sense. Prussia, while still bitter and militaristic, was defeated, and was home to old German nobility who weren't very keen on listening to some upstart Austrian commoner whose buddies wear weird armbands (and hate Jews for no reason and communists for several reasons of varying legitimacy, but that didn't really matter as much to them, since a lot of them did as well).
On the other hand, the Bavarians, similarly bitter after losing the war (albeit less militaristic), were much more welcoming of weird mustache man and company. He was from Austria, whose culture, religion, and dialect was more similar to theirs than that of the Northern Germany (I'm learning about Germany in school. I know about this stuff). His lack of noble title did not mean nearly as much, and a lot of his ultraconservative ideals appealed to the Bavarians. Bavaria really was the Nazis' heart of power and support in Germany, as unpleasant as it would be for modern Bavarians to admit.
So, what if, in this timeline, the Allies blamed Bavaria instead of Prussia. They could say "Bavarian Reactionaries" were responsible for WW2 as easily as they could blame "Prussian Militarism". What if they did? What would they do to Bavaria? How would the cold war be effected? What would modern Germany be like?
